who has operated the same and also to show the exact time when such operation was effected. o

7 The present invention relates to a recording door lock, the same being adapted to be operated by any one of a series of keys, or any one of a series of combinations for which the lock may be constructed,'said keys or combinations determining what character will appear upon the record when the lock is operated. In addition to .the impression showing the key or combination employed, which key or combination is assigned to some particular person, l have provided an hour and a minute wheel, and alsoa day and a month wheel, said wheels carrying impression characters upon their peripheries, which characters are adapted to be lined up so as to give a printed record showing the minute andl hour, as well as the day and month when the impression was made.

My invention is an improvement over that described in the patent to Allen De Vilbiss,

No. 735,034, dated July 28, 1903, said improvements having for their objects the modification of the structure shown in said patent whereby the device is rendered more accurate and certain in its operation, and more economical in its manufacture.

is a side view of the bar shown in Fig. 11; Fig. 13 is a sectional view through the key barrel and cam, the same being taken on line 1313 of Fig. 2; Fig. 1a shows a modification of the connecting mechanism between the key barrel and cam, this structure being preferably employed when the said barrel and cam are applied to a thick door; Fig. 15 is a sectional view taken on line 1 5 l5 of Fig. 14:; and Fig. 16 is a transverse section taken through the center of the locking bolt.

Referring nowqto the drawings, in which similar reference characters designate correspondingparts throughout the several views, 1 represents the casing of the lock, the same being a rectangular box that is open at ts front, said front being adapted to be closed by the-c over 2. The casing 1 is intended to besecured to the door of a store or other building in a manner common to door looks,

within the casing almost midway between its upper and lower ends is a locking bolt, sa1d bolt comprising an enlarged engaging end Specification of Letters latent. pm m a mm, an, gene),

' 6, the .ent carries the 3 and an operating portions, said portion 1 being slotted at 5 in order that it maybe properly guided within the casing, a screw 6 extending through the slot for that purpose. I

Substantially at the center of the portion 4 and on its lower edge there is formed an irregularly-shaped slot or notch 7, within which slot or notch projects from therear of the lock the stepped cam on the end of a bar 8. This stepped cam is normally held in its extreme rearward position by a spring 9 which bears upon its forward end, as shown particularly in Fig. 7 The said cam is located so as to be engaged by the forward ends of the keys 10 as they are inserted'inthe lock, or the keys may engage with the end of a bar that is connected with the cam, said keys pushing the cam in- .wardly distances depending upon the length of the extended portions 11 on the keys. Fig. 2 shows a key which has practically no extension of this character, and which, therefore, moves the cam inwardly. to its slightest extent,,while Fig. 7 shows a key with a longer extension, said key having pushed the cam inwardly to its maximum extent. As shown in the drawings, a lock of the ordinary Yale type is employed, although this is obviously a matter of choice with the manufacturer and user.

The stepped cam 8 is provided at diametrically opposite points with slots 12, into which project lugs that are formed on a tumbler 13 that surrounds the cam, such a construction forcing the tumbler to turn with the cam. In Fig. 13' I have shown a section through the rear end of the cam and the forward end of the key barrel 1 1, from which it will be seen that the said barrel has extensions 15 (see Fig. 13) which project into the slots 12 on the cam, thus forcing the latter to turn with the barrel, the rotation of the key being thus transmitted through the barrel and'cam to the tumbler 13. One side of the stepped cam 8 is flattened, as is indicated at 15', and when the tumbler is in its normal position, an arm of the printing segment 16 lies against said flattened side, being held thereagainst by a coiled spring 17. This printing segment is mounted to turn upon a stud 18 that projects from the rear of the casing substantially above the stepped cam 8, said cam projecting between the arms of the segment. As appears most clearly from Fig. 6 of the drawings, the segment 18 is provided on its lower end with a series ol -impression-characters 17', said characters designating the different keys with which the lock is designed to be operated. As each key is assigned to a particular person, it will be seen that said characters 17 designate the persons to whom such keys are intrusted. As shown in said Fig. letters A, B, C and D, although it will be obvious that other characters, such, for example, as numerals, may be used instead. As will hereinafter appear, these characters are to be used in connection with a printing platen to print a character upon a record strip. I desire to state, however, that dilierent kinds of impression devices may be used instead of printing type, it being within the scope of my invention to provide the segment 16 with any form of character impressing devices. I may also state that it is within the scope of my invention to operate the lock by other means than the keys shown, such, for example, as the ordinary combination lock,'said lock being designed to move the stepped cam 8 to distances corresponding to' the combination employed. From this description it will be understood that the stepped cam is normally retracted by the spring 9 so that the smallest part a (Fig. 7) of the cammed end thereof contacts with the segment. Then the key with no extension shown in Fig. 2 is employed, the stepped cam will be turned, but it will not be moved forwardly and, consequently, the segment will not be swung at all. The key with the shortest extension will thrust the cam outwardly until the step b thereon, (Fig. 7), will be in position to engage and move the segment. The steps 0 and d of the plunger are likewise brought into operative position by their respective keys, and when the latter are turned the segments will be swung to bring charactersthereon corresponding with the keys employed to the printing line. The rear side of the segment 16 is provided with a flange 19 through which are cut slots 20, the flange between said slots forming teeth 21, for a purpose hereinafter stated.

Suitably mounted upon the back of the casing, and extending vertically therein there is a platen bar 22, said bar being shown in detail in Figs. 11 and 12 of the drawing. This bar is normally pulled into its lowermost position by means of a spring 23 that is attached to its lower end and it is adapted to be moved upwardly by meansof a lug'24 on the tumbler 13. In order that the tumbler may properly engage with the bar, the latter is provided with a rounded enlargement 25 in which is formed a cam opening 26. This opening is circular in contour except at its upper end where it is formed with a straight edge'27 that is substantially perpendicular to the axis of the platen bar.

When the platen bar is in its normal position, as is shown in Figs. 3 and 4, the cam 8 projects substantially through the center of the cam opening, and the lug 24 contacts with the lower rim of the opening 26. This lug travels in contact with the inner rim of this opening, and, as it reaches the straight edge 27, the platen bar is gradually lifted until it assumes the position shown in Fig. 5. 1

As the lug 24 continues its movement, the platen bar is again lowered to its original position. Toward its lower end the platen bar is provided with a forwardly extending platen 28 which projects opposite the impression characters 17 on the type section. A short distance above the platen the bar is provided with a guide pin-29, said pin being adapted to move between the'notches 21 of the type segment as the platen is lifted. These notches are beveled as shown in Fig. 6; and as the pin moves between them the segment will be shifted thereby so as to line up the type on the segment to the exact printing position. The platen bar is guided in its movements by the stud 18, heretofore referred to, and by the studs and31 that project from the rear of the casing. As appears from the drawings, the stud 30 has a flange that projects over'the platen bar and holds it down into position.- In order that a more satisfactory impression may be made, the platen 28 is provided with a suitable pad 28'. i I

The portion 4 of the locking bolt passes over the circular enlargement 25 of the platen bar, and moves transversely thereto, said movement being efiected by the lug 24 on the tumbler. As the. lug turns about from its position shown in Fig. 4, the bolt will not be moved until the lug reaches almost itsextreme upward position, when it will contact with thelefthand edge of the slot or notch 7. Prior to this engagement the lug contacts with a projection 32 on a locking pawl 33 that is pivoted to the looking bolt at 34, said pawl being held down- .wardly in the position shown in Fig. 4 by a spring 35 that is secured at one of its ends to the pawl and bears with its opposite end against the enlarged head 3 of the bolt. Near the right hand end, this pawl is provided with a tooth 36 that is adapted to engage with the sides of a post'37 that projects forwardly from the rear of the casing.

hen in the position shown in Fig. 4, this tooth 36 and post 37 will prevent the out-; ward movement of the locking bolt unless the pawl be first released so as to clear the tooth from the post When the bolt is moved to its outer position, this pawl drops down and engages with the left hand side of the post, as indicated in dotted lines in Fig. 5, and when in this position it will prevent the inward movement of the bolt until the pawl is again lifted. Just before the lug 24 engages with the projection 32, it contacts with the straight edge 27 of the cam opening 26 in the platen bar, and lifts the'platen intoprinting position as shown in Fig. 5. The engagement of the lug with the left hand side of the notch 7 continues to move the bolt outwardly until the lug passes the point 38 of said notch, after which the further movement of the lug will have no effect upon the locking bolt. From this descrip-' tion it will be seenthat prior to'the move ment of the locking'bolt, the platen has been raised to make an impression. Likewise, if the tumbler were turned in the opposite direction after the bolt had been entirely shot the lug would engage with the straight edge 27 of the platen bar, and would move the latter tomake an impression before the bolt had begun its movement. -A printing impression is thus made each time the lock is operated to lock or unlock the door; and it is even operated if the tumbler is arrested and returned, provided its movement has been suificient to lift the locking pawl 33 so asto release the bolt.

The post 37 above described, serves as a means of attachment for the spring 9 which retracts the plunger 8. In order that the platen bar will not interfere with the locking bolt, the latter is cutaway on its rear side to accommodate said bar, as is shown in Fig. 16.

The paper strip upon which the record is printed is shown at 39, and it is carried from the reel 40 over guide rods 41 to a reel 42 non which it is wound. An inking ribbon 43 is carried from; the reel 44 over guide rods 45 to the receiving reel \46. The reels 42 and 46 are each turned to wind the paper and the ribbon thereon by means of a long pawl 47 that is attached at its upper end to and 3-, the cam projection 50 extends into this cutaway portion so that the pawl 47 is lifted. Immediately upon the movement of the tumbler from the position shown in these figures, the lug 24 pushes the cam lever 48 aud t-he pawl downwardly. This pawl has a pair of teeth 53 and 54 which engage. with ratchet wheels 55 and. 56 upon the reels 42 and 46 respectively. As will be seen from Fig. 4, the teeth on the ratchet wheel 56 are greater in number than the number of the I teeth on the ratchet 55, in order that the paper strip may be fed a gr'eater distance than the inking ribbon. and 58 engage with the ratchets 55 and 56 respectively to prevent backward rotationof thereelsfsaid pawls being held in engaging position by a single spring 59 connected to the tail-ends of these pawls.

The time recording mechanism consists of an hour and minute wheel 60 that is jour-.

naled upon the stud 3O heretofore referred to, said wheel carrying upon its periphery Detent pawls 57 numerals 61 which represent the hours and the minutes, said numerals being arranged as follows :1, 1 1 1* 2 etc, there being 'a different set of numerals for each quarter hour, and there being two series of numerals representing day and night. These two series of numerals are consecutive with respect to each other, and the individual numerals of each set are consecutive, that is, they run from 12 to 12 by quarter-hour periods in each series, the one series following the other. The arrangement of these numerals is clearly seen from an inspection of Fig. 10 of the drawing. Secured in any suitable manner to the wheel 60 on its under side is a ratchet wheel 62, said Wheel being provided with one tooth for each quarter of an hour that is represented upon the hour and minute wheel. Said wheel is turned intermittently at intervals of every, fifteen minutes by means of a clock mechanism indicated generally in Figs. 2 and 3 by reference sign K which is located, preferably, in the upper part of the casing 1; This clock mechanism may be of any suitable type, and it is not deemed necessary to describe the same in detail. 63 represents a shaft of this clock which correspondsto the arbor for the min- -ute wheel in the ordinary clock, said shaft carryingupon its front end an indexhand or pointer 64; for a purpose hereinafter stated.

. Near its rear end this shaft carries a wheel carries a pawl 68 that is pressed downwardly by means of a spring 69 so that a tooth 70 on said pawl will be held in engagement with the teeth of the ratchet wheel 62. The arm 66 is pressed into engagement with the cam projections on the wheel 65 by means of a spring 71 that bears against the arm near its lower end. Bearing in mind that the shaft 63 with the cam wheel rot-ates once each hour, it will be understood that every fifteen minutes the arm 66 will be cammed over so that the tooth '10 of the pawl will engage behind a tooth of the ratchet wheel 62, and that as soon as the curved end of this arm passes the projection on the wheel 65, the pawl will be kicked forward by the spring71, which action will result in turning the ratchet wheel, and the hour and minute wheel one numeral forward. In order to prevent the kick on the pawl from overthrowing the ratchet wheel, a post 710 i is projected upwardly from the back of the casing in a position to be engaged by the end of the pawl 68. This post is flattened on one side, and the end of the pawl is beveled, with the result that, as the pawl moves to the eat/,aro

left in Fig. 3, a will be jammed into the ratchet wheel and will thus arrest the latter just after it has moved the distance of one tooth. The ratchet wheel is prevented from turning in a reverse direction by a detent pawl 72 that is mounted on a stationary part withdrawn until it is freed from the post 710, after which the wheel may be set to print any hour desired.

It is desirable that the record strip should show not only a character for indicating the person who has operated the lock and the hour and minute of such operation, but that it should also show the day and the month when such operation-was efiected. To accomplish this result, I provide a day wheel T3 and a month wheel 74 supported by a frame piece 5, said frame piece being fixed to the side of the casing at the points 76. The day wheel is secured to the end of a shaft 77, and the month wheelv is loosely journaled thereupon. This shaft projects beyond the frame piece 75, and has a dial hand 78 attached to its end, said hand turning about over a dial 79 that is carried by the frame piece. By turning this hand so that it points out the proper number on the dial, the ,day wheel will be set so that the samenumber on the periphery thereof will be brought opposite the printing point. Similarly, the month wheel 74 is connected with a 'dial hand 790 that is adapted to be turned about over a month dial 80 on the frame piece 75; and when this hand is turned toward a certain number on the month dial, a corresponding number on the periphery of this wheel. will be brought to the printing point. From this it will be seen that manually operated means are provided for setting the day and month wheels to proper positions. It is desirable, however, that the day wheel be automatically set, and I therefore place the same under control of the hour and minute wheel, so that upon a complete rotation of said wheel, the day wheel will be turned forward one step. This controlling means consists'of a lever 81 that is mounted to rock upon the inner end of the shaft 77 and a cam 82 that is secured to a sleeve 88 that is carried by the hour and minute wheel 60, said cam operating as the hour and minute wheel is turned to move the lever 81 about its pivot. The lever is held against the edge of the cam by a spring 8 1-. The lever 81 carries a pawl that is adapted to engage with the teeth of a ratchet wheel 86, said ratchet wheel being secured to the inner side of the day whee A detent pawl 87 engages with the ratchet wheel 86 to prevent backward movement thereof. From this description, it will be understood that as the wheel 60 rotates, the cam 82 will gradually turn the lever 81 about its pivot, thereby causing the pawl 85 to slip backwardly and engage with a tooth of the ratchet wheel. This operation 'co'ntinues until the point of the cam 82 passes the end of the lever 81, when said lever will be thrown backwardly by the spring 84,

which movement will cause the pawl 85 to,

turn the day wheel so as to bring another numeral to the printing point.

The cover plate or lid 2 is adapted to cover the entire front of the lock, the same being held in position by lugs 88 at one end of the casing which engage with sockets in y a flange of the lid, and.by a lug 89 which engages the bolt of a lock 90 at-the opposite end of the lid, said lock being of any suitable character and being operated by a key in any well-known manner. Near its upper end the lid is provided with a window 91 that is opposite the hand 64 on the shaft 63, a said hand turning \with said shaft, and

tors-Patent is pointing toward figures in a dial 92 on the front plate of the clock mechanism, said dial being provided with numerals representing 1 hen the lid is removed from the minutes. the casing the shaft may be turned-by the hand 64 so as to set the clock to any minute that may be desired. This lid is also provided near its center with an inwardly extending circular flange 93, the lower end of which is covered by a glass 94. This glass is opposite the rim of the hour and minute wheel 60, which rim is provided on the side next the glass with characters 95 representing the hours, said characters being so positioned with reference to those on the periphcry of this wheel that the observer may see through the window of the casing the hour that has been brought to the printing point. The two windows 91 and 94, therefore, are so positioned that both the hour andthe minutecan be read directly from the lock,

know in case the lid 2 has been removed by c any unauthorized person, said lid is provided with a registering device, which is indicated at 96, said device adding by successive' operations the number. of times the lid has been opened.

In Figs. 14 and 15, I have shown a modified form of connection between the keybarrel l4 and the tumbler 8, in which the key 10, pushes against a bar 97, said bar being secured at its forward end to the tumbler. While any suitable form ofsecuring means may be employed, I prefer to use that shown tumbler is split so as to receive the forward end of the bar; The split portions of the tumbler are clamped against the bar by a nut 98 that is secured upon the former, which is slightly tapered to receive it. At

its opposite end the bar enters a slot 99 in the key-barrel, the said end being provided with lugs 100 which extend outwardly in the slot to compel the bar to rotate with the barrel. To prevent the bar from disengag ing entirely from the barrel, the end of the latter may be provided with a cover plate 101 with which the lugsengage'.

From the foregoing description, it will be seen that I have invented a door register that is simple in construction and positivev to be understood that I donot propose to I be limited to the details described except as the same may be included in the claims or rendered necessary by the prior state of the art.

Having thus described my invention what I claim as new and desire to secure by Let- I. In a recording lock, a locking bolt,
